Latest Patents

Henaff's latest patents include a demodulation filter for signals modulated in a binary frequency manner. This invention relates to a filter designed for demodulating signals that are modulated in frequency by switching between two frequencies, F.sub.a and F.sub.b. The filter utilizes a piezoelectric crystal to produce two surface wave filtering units, each equipped with a transmitting and receiving transducer featuring interdigitated electrodes. The design of the receiving transducers is meticulously calculated to optimize performance based on the frequencies involved.

Another notable patent is her elastic surface wave recursive filter. This filter comprises at least one delay line formed by two elastic surface wave transducers, which is looped externally by an amplifier. The filter also includes a means for introducing an elastic surface wave into the line and a third transducer functioning as a transversal filter. The transfer function of this filter is expressed in the form P(z)/Q(z), where both the numerator and denominator are independent.
